Objective: We investigated the accuracy of imaging modalities in diagnosis and outcome of otitis media with effusion by correlating the imaging findings with the preoperative otomicroscopic examinations, tympanometric results, and intraoperative findings in patients who underwent cochlear implant surgery.

Methods: The results of the preoperative physical examination and intraoperative findings of patients younger than 18 years who underwent cochlear implant surgery at a single tertiary institution were recorded from their medical charts. Tympanometries, which were performed in maximum 1 week prior to imaging modalities, were analyzed.

Article Synopsis
  • The study explored the relationship between oral microbiota dysbiosis and oral cavity cancers by comparing patients with cancer to matched healthy controls.
  • Data was collected through questionnaires, clinical examinations, and saliva DNA sequencing to analyze the microbial composition.
  • Results indicated that cancer patients had poorer oral health and a distinct microbial profile, with specific bacterial species linked to the disease, suggesting interactions between oral bacteria and cancer development.

Objectives: The important roles of integrins in tumor invasion, migration and proliferation are well known. In this study, we investigated the presence of integrin α3 and β1 receptors in tumor tissue, metastatic lymph node (LN) and normal thyroid tissue of patients diagnosed with thyroid cancer (TCa) and showed the prognostic and diagnostic value of these molecules as well as peptide-receptor.

Methods: Sixty-one patients with TCa were included in this study.

Objective: Mesna triggers chemical dissection in tissues by breaking down disulfide bonds and is used during surgical dissections in several areas. In this study, we aimed to investigate the effect of submucosal mesna infiltration on microflap elevation and the histopathological findings of its effects on the vocal fold lamina propria in a rabbit model.

Methods: Eight adult male New Zealand white rabbits were used in the study.

Objective: Malignant otitis externa (MOE) is a serious disease affecting mainly the elderly diabetic patients that may result in mortality. It was aimed to evaluate the relationship between treatment responses and clinical and radiologic parameters among progress of the disease. Secondary aim was to present our clinical outcomes in the treatment of malignant otitis externa.

Objective: To investigate the prevalence of tonsillar human papillomavirus infection in İstanbul, the most populous city of Turkey.

Methods: Tonsil specimens were obtained from 206 cadavers aged 18 to 89 years. Tonsillectomy was performed during routine autopsy for each subject in the 24 hours after death.

Objective: To investigate the presence of sulcus vocalis in patients who underwent phonomicrosurgery due to benign vocal cord lesions.

Methods: Between January 2013 and June 2018, the records of 133 patients who underwent operations for benign vocal fold pathology were retrospectively reviewed. Intraoperative findings of the patients were noted.

Objective: To compare the acoustic parameters and the cost effectiveness achieved after endoscopic cordectomy using radiofrequency microdissection electrodes (ECRM) with those of transoral laser cordectomy and radiotherapy.

Methods: The study included 81 disease-free patients previously treated for early larynx carcinoma (30 with ECRM, 27 with transoral laser cordectomy, 24 with primary radiotherapy). Post-treatment voice analysis was performed in all patients.

Purpose: Pediatric population may be more prone to complications in comparison to adults because of the variability of developmental changes of paranasal sinuses and skull base. Knowledge of standard columellar distances regarding age in addition to anatomical landmarks is an important guide during functional endoscopic sinus surgery. We aimed to identify standard distances from columella and anterior nasal spine to the anterior and posterior border of frontal and sphenoid sinus ostiums and provide an objective reference graph in regard to age in children.

Objective: The study aimed to evaluate the existence of sex hormone receptors in the subunits of vocal fold.

Study Design: This is a cadaver study.

Methods: The androgen, estrogen, and progesterone receptors were examined in the epithelium (EP), superficial layer of the lamina propria (SLP), vocal ligament (VL), and macula flava (MF) of the vocal folds from 42 human cadavers (21 male, 21 female) by immunohistochemical methods.

The external auditory canal contains ceruminous glands, which are modified apocrine sweat glands, along with sebaceous glands. Tumors that originate from ceruminous glands are very rare; thus, the classification, clinical behavior, and management of these tumors remain debatable. Here we present a case of ceruminous adenocarcinoma arising from the external auditory canal.

Article Synopsis
  • A study aimed to analyze the occurrence and histopathological characteristics of sulcus vocalis in a cadaver population revealed that it is present in 39% of cases, with a higher frequency in men compared to women.
  • Out of 200 vocal folds examined, 57 exhibited sulcus, with various types identified; histopathological examination confirmed 12 cases that appeared normal under macroscopic evaluation.
  • The findings suggest that sulcus vocalis is common across different age groups, highlighting the need for improved diagnostic tools and strategies for effective management in living patients.

The ideal goals of chronic middle ear surgery should be the permanent removal of disease and the preservation of good hearing function. The postoperative outcome of hearing and the status of middle ear after canal wall-down tympanoplasty with primary ossiculoplasty were studied in 192 ears with chronic middle ear disease. Cholesteatoma was present in 121 (63.

Sulcus vocalis is the presence of a groove extending along the vibratory surface of a vocal fold and may result in dysphonia. Depending on the level of severity, this condition may require treatment involving complicated surgical techniques. Cases of sulcus vocalis are classified as physiological, vergeture, or pouch type.
